I will say this, however: Around age 30 my metabolism just about bottomed out (at least it feels that way) and I notice now that I get cold sometimes whereas 5 years ago, I would have to be wet and naked outside in the middle of winter to get a chill. So, enjoy it while you can, Jack.
What about you, Dub? Do you find you get colder now that you turned 85 years old?
